Almost anything in Heroic Ragnaros can not be done in a 200+ms latency. See the video.

Nice find.

I'm not going to watch the whole 30 minute tutorial but from the first 6 minutes of it I don't see anything that would be impossible to dodge even with a .5 second delay if you want to consider someone with a rather high ping.

You missed most of explanations as to why there's no room for error in most of the encounter. World In Flames in particular requires tight maneuvering and good timing (that can't afford to be ruined by high latency, and delays in use would trivialize that part of the encounter).

Mind you that any additional damage from something like WiF will stress the healers, and unlike XIV or XI where raid damage (as in damage taken by everyone as part of the encounter) isn't very common, WoW's taken to using raid damage as a means to put stress on resources and challenge the healers on top of whatever mechanics involve the tank(s) during the boss fight.

Waiting for the "Omg not WoW" response...

I'm waiting for someone to say "it sounds too complicated". XD
